产品概述 返回TOP
The CXAD33100 converts stereo single-ended analog input signals into 24-bit I2 S digital audio data through on-chip anti-aliasing filter, multi-bit - modulator, decimation filter and high-pass filter which removes dc offsets. The CXAD33100 supports sampling frequencies from 8 kHz to 96 kHz and offers 128 FS, 256 FS, 384 FS or 512 FS system clock operation modes depending on sampling frequency and master/slave mode selection. The CXAD33100 is suitable for digital audio media applications which require high performance A/D conversion and low system cost.
